IMPROVEMENT IN WEATHER-STRIPS;

Specification forming part of Letters Patent No. 18h/1,691, datedNovember 28., 1876; application filed 4 August 30, 1876. Y

To all whom it may concern.:

Be it known that I, JOSEPH BALDWIN, of Hopedalc, in the county ofHarrison and' State of Ohio, have invented certain new and usefulImprovements in Weather-Strips; and l do hereby declare that thefollowin gis a full, clear, and exact description thereof, which will,enable others skilled in the'art to which it pertains to make and usethe same, reference being had to the accompanying drawing, and to theletters of reference marked thereon, which form a part of thisspecification.

My invention relates to improvements in weather-strips, and has for itsobject to furnish a cheap and simple device capable of being attached toany door without cutting or mortising the latter, and that will beautomatic in its operation.

, It consists in a notched r=recessed Weatherstrip, provided with arear-side projection, and journaled in with capability of a horizontaltoand-l'ro movement between a pair of lugs or brackets, one of which isrecessed to receive the rear side projection or stop and it c'onsists,further, in other improvements, all of which will be hereinafter morefully explained.

In the drawings, Figure l is a vertical section, and Fig. 2 is aperspective, of a door having my improved strip applied thereto; andFigs. 3, 4, 5, 6, and 7 are detail views of parts.

a is the door, hinged to the frame al. a? is the threshold-strip, and a3is a portion of the lower end of the jamb, or part of the doorframeagainst which-the door shuts, with a portion ofthe threshold-stripattached thereto. b b1 are the brackets or lugs in which theweather-stripisjournaled. Theyare provided with suitable flanges b2,which give the necessary facilities for fastening to the door. They maybe made of any desired ornamental form,-

with their upper edges made sloping to give pitch or slant to the hoodor cover b3, placedthereon for the protection of the strip against rainor other injuring cause. are connected by, or support in suitablebearings, a rod, b4, to which the lower edge of the hood b3 is secured.They are provided with the bearings b5, in which the axes of theWeatherstrip turn. The bracketvb is provided on its inner face with therecess c, in which aV side projection, hereinafter described, on the,

Their outer ends weather-strip, engages, for the purpose of holding thestrip elevated when the door is'open.

The bearings bi and the -recess c may be ar-' ranged'in relation toeachI other, so that a straight convex or concave strip may begemployed,instead of the form shown in Fig. l, d is the weather-strip, which litsneatly between the door-posts, aud, when thedoor is closed, vcovers theopening above the thresh old strip. Its end is rounded or slightlycurved, as shown at d1, so as not to interfere with the jamb in theopenig or closing of the door. Its rear side is shortened by having theportions dzd3 cut from the ends, which permits the setting of thebrackets b bl far enough in on the door so as not to strike thedoor-frame, and so that it Will have a horizontal to-andfro movement onits axes d4 d4, sliding in the bearings b5, whereby it is automaticallyadjusted to the-curvilinear movements of the door in opening and closingthe latter. In cutting away the portion d2, a projection, d5, is left onthe weathecstrip, which. projection engages in the notch c, and, whenthe door is open, holds the strip'in the horizontal or elevated positionshown in Fig. 2. Instead of having the projection d54 a part of thestrip, as above set forth, I prefer t'o attach to the under side of thestrip, by suitable rivets, a long spring, d5, secured near the center ofthe strip, its end projecting, as shown in Fig. 6.

-When the door is open, the spring will yield to any pressure on theouter Wing of the strip, and will prevent injury thereto. The .sheetmetal hood or cover' b3 is secured to the cross rod b4, as hereinbeforestated, and to the door a. It rests on and takes the form of the top ofthe brackets b b1.

long enough so that when secured to the door Its upper end 116 is madeby nails or screws it may be turned down over and protect the latterfrom the Weather, as shown. The extended end may be so formed that whenturned down it will present a neat, ornamental appearance. y c is anangular block, made of metal or other suitable material, and secured tothe threshold-strip, for the purpose .of elevating the weather-strip as'the door is opened. It is arranged so that it will be immediately behindthe Weather-strip when the door is closed, and so that the slightestmovement of the door outward from the jamb will conse the elevationuofthe weather-.ship into aliorizontal` position. .By preference Ilform itwith the lngY which islet into the jamb,`

and provides facilities for fastenin gs, and also makes abearing-surface, against which-"thrrounded end d1 moves, and thusprotects the jamb from being wonn away.f fmanietallic bearing placed inthe post al to protect the latterfrom being worn by the frequentstriking'of the weather-stripthereagninst." y r The operation of thedevice is as follows: The weather-strip being elevated, as shownin Fig.2, by closing the door the end d5 comesin contact with the post a), andpushes the strip toward the jamb, and just as the door is closed theprojection d5 becomes disengaged, and the strip drops into the positionshown in Fig. `1. i the block aelevates i When the door` is opened,

the strip toa horizontal position, and as the doox` swings back, the endd1, bearing against the jamb a3, moves the strip towaizdv the lng b, i

cess aand hold theisttip elevated;
